Register Name:
Access Type:
• CKS: Transmit Clock Selection
• CKO: Transmit Clock Output Mode Selection
• CKI: Transmit Clock Inversion
0: The data and the Frame Sync signal are shifted out on Transmit Clock falling edge.
1: The data and the Frame Sync signal are shifted out on Transmit Clock rising edge.
CKI affects only the Transmit Clock and not the output clock signal.
• START: Transmit Start Selection
